[1] He was the fourth son of Sarah Mogridge and her husband John Gee (died 1631), the latter being parish priest of Dunsford, Devon, making Orlando brother to the cleric and anti-Catholic writer John Gee.
[2][3] In the 1650s he began to ally himself with the House of Percy in general and Charles Seymour, 6th Duke of Somerset in particular.
[1] His only notable intervention in the House of Commons during his first term was to safeguard his own business interests in two paper mills in Buckinghamshire from a perceived threat from a bill promoting production of white paper, but neither of two clauses moved to mitigate this passed the House.
He opposed attempts to replace the Admiralty commissioners in a 21 November 1692 debate and seconded a motion on 19 January the following year that the 6th Duke of Somerset's chaplain give the annual sermon commemorating the execution of Charles I.
He initially supported the Triennial Bill but had turned against it by the time of a speech on 2 February 1693 in which he stated it was "an invasion on the [royal] prerogative".
